摘要： A braking system includes a power supply supplying electrical power, and first and second brake components at least partially operated by electrical power. A first power supply network electrically connects the power supply and the first brake component, and a second power supply network electrically connects the power supply and the second brake component, the power supply networks being adapted to transmit the electrical power from the power supply to the first and second brake components respectively. An auxiliary power supply link is activatable to electrically connect the first power supply network and the second power supply network only when a failure occurs in one of the first power supply network or the second power supply network, the auxiliary power supply link adapted to transmit the electrical power between the first power supply network and the second power supply network only when the failure occurs.

摘要： A brake by wire system is integrated with a brake transmission solenoid interlock (BTSI) unit to prevent a vehicle transmission from being shifted out of a park mode into a drive mode until a brake system operational state is determined. The BTSI is activated by a supplemental control unit, which generates a transmission release signal generated by a controller in response to simultaneous presence of a brake intent signal from one or more brake pedal sensors and a determination of an operational state of the brake system. The supplemental control unit includes a switch responsive to the transmission release signal to close the BTSI activating circuit and permit release of the transmission. In a split brake system with two brake controllers, the supplemental control unit may include a switch controlled by a logic (OR, AND) circuit or a pair of switches in an equivalent logical circuit configuration.

摘要： A brake system for a motor vehicle includes a pedal unit through which activations of a brake pedal are sensed, two central units and electromechanical brake actuators assigned to wheels. Sensor signals are transmitted to the central units by the pedal unit. In the central units, brake engagement setpoint values are calculated and serially encoded together with the sensor signals, and control signals for supplementary brake functions are generated. The encoded signals are each transmitted to two respective brake actuators through data buses. The control units of the brake actuators make a majority decision and control the brake actuators accordingly.

摘要： An anti-lock braking system includes three integrated circuits (an integrated voltage regulator and two different microcontrollers) which perform different functions but share the tasks of detecting malfunctions and shutting down the system when malfunctions are detected. The two different microcontrollers perform different functions, have different circuitry, and execute different software. Typically, a first microcontroller receives wheel sensor signals, calculates wheel velocities and accelerations, and operates mechanical devices which control braking. A second microcontroller executes the main anti-lock braking software and determines from the velocities and accelerations when brakes should be released. All of the integrated circuits monitor each other and the other elements of the anti-lock braking system to detect malfunctions. Multiple shut down methods are provided so that a single chip failure can be safely handled. The three integrated circuits can be fabricated using different device technologies and design rules so that the operating environment of the anti-lock braking system is less likely to cause simultaneous failures in multiple integrated circuits.

摘要： A unified control device for a vehicle including an anti-skid braking system and power steering control system is controlled by two microcomputers (4B and 24B). On the basis of the outputs of the torque sensors (1a and 1b, etc.), the first microcomputer (4B) determines the driving direction and torque of the DC motor (9) providing the assisting steering torque for the steering wheel, and outputs the torque signal (T) and the first direction signal (D1) for the DC motor (9). The second microcomputer (24B) generates the brake operation signal (B) on the basis of the outputs of the road wheel velocity sensors (21a through 21d) and the brake switch (22). Further, on the basis of the output of the torque sensors (1a and 1b), the microcomputer (24B) determines the direction of the DC motor (9), and outputs the second direction signal (D2). The motor drive circuit (8) drives the DC motor (9) in accordance with the torque signal (T) and the direction command signal (D), which is output from the AND circuit (40) only when the first and second direction signals (D1 and D2) coincide. Further, the microcomputers (4B and 24B) output first and second fail-safe relay energization signals (F1 and F2), respectively, when the power steering control system and the anti-skid braking system are judged to be operating normally. The power supply control circuit (42) immediately opens the fail-safe relay unit (6B) when neither the first and second signals (F1 and F2) are supplied. However, in the case where only one of the first and second signals (F1 and F2) are supplied, the power supply control circuit (42) defers the interruption of the fail-safe relay unit (6B) until the vehicle stops.

摘要： A brake pressure controller, for example an anti-lock control system, is disclosed which includes fault monitoring. If a fault occurs, limited control operation is maintained initially and only later is the controller shut down. The limited control operation and the shut-down controller are indicated by different warning signals.

摘要： An anti-skid control circuit for a wheeled vehicle and a method of processor computation confirmation within such an anti-skid control circuit includes the confirmation of proper processor operation only at a certain one of the computation values. Rotation of a vehicle wheel provides a pulse train the repetition rate of which is indicative of the vehicle speed. A sequence of program steps is repetitively executed in a mircroprocessor (17) over a fixed time interval with the microprocessor (17) repeating that same predetermined sequence of program steps during each successive said fixed time interval. A second pulse train is provided having one pulse for each repetition of the sequence of program steps. The speed of at least one vehicle wheel is repetitively computed according to the repetition rate of the first pulse train and the repetition rates of the first and second pulse trains are compared, and corrective action is initiated in the event that the compared repetition rates differ by more than a prescribed amount. The comparison is effected only at a certain specific wheel speed. Alternatively, a computed wheel speed may be compared to the fixed time interval and the anti-skid circuit allowed to continue in operating only so long as the compared wheel speed and time interval are within predetermined limits of one another. Again, the step of comparing is effected only at a certain specific wheel speed.

摘要： To counteract the tendency of over-steering when a vehicle operates in a curved path, and one of the wheels--typically the wheel at the inner side of the curve exhibits a tendency to block and, then, braking pressure is reduced to one of the front wheels only, the braking pressure applied to the rear wheel or wheels is reduced. If braking pessure is reduced to both of the front wheels, braking pressure being applied to the rear wheels is controlled, independently, in accordance with anti-brake lock control considerations, which have priority over dropping of braking pressure to prevent over-steering.

摘要： A method and a circuit configuration for suppressing sporadic interferences in the processing of data by means of two circuit systems (2, 3, MC1, MC2). The circuit systems redundantly process the data and, for the purpose of detecting errors and interferences, between the circuit systems data (D1n, D2n) is exchanged and compared for agreement. If the comparators (15, 16, 25', 41.2, 43.1, 46.2, 49.1) detect differences the transferred data will be taken over and the data processing will be continued with the transferred data. This takes place in several consecutive cycles. As soon as the predetermined scope or a predetermined number of cycles with differences between the compared data is exceeded an error will be evaluated and indicated. The circuit configuration is suitable for increasing the tolerance of electronic control circuits (ER) of the type for slip-controlled brake systems.
